Tourism is one of the economic driving forces of Spain: the consolidation of existing tourist destinations and new market niches encourage an upward trend of tourism. The economic impacts produced by tourism are one of the major concerns of the authorities; the question is whether it is possible to continue growing without compromising our environment. This work attempts to answer this issue by analysing one of the tourism segments with higher growth in recent years: rural tourism. Using a model of partial least squares (PLS), we will analyse the environmental impacts from the point of view of the supply and its relationships with the environmental management conducted. We will also analyse the rural establishments from a global point of view and, depending on their category, explain the factors which determine the sustainable behaviour of providers, and identify that the establishments of low categories have a more sustainable conduct.
